It was removed since version 4.63. See the note: "Removed Andernach Grasshopper (is just a HurdleColourChanging Grasshopper)"
So, it looks that you can test problems with AG using command "HurdleColourChanging G" (I am not tested it yet).

So it is perfect (G+HurdleColourChanging).

I don't understand why this lengthy description when AG (Andernach Grasshopper)
was very handy!
Will it not be better to reintroduce it?

The advantage of this way of naming the "Andernach Grasshopper" is that we now have the Andernach variety of almost all hoppers, not only the grasshopper, without having to introduce a separate abbreviation for each and every one.
In other words, "HurdleColourChanging" is seen as a property of some pieces, like neutral or paralysing or magic, not as a special kind of piece.
(And by the way, the American inventor of the Andernach G intended this to be a general property, applicable to all hoppers.)

Yes. Kjell is very correct. "Hurdle color changing" is after all a quality (or attribute) like "paralysing". Since hurdle color changing option is already available in Popeye there is no need for a special piece "AG".
